Abstract
Distinguishes between communication apprehension (CA), the fear of actually communicating, and communication development, the ability to maintain and improve performance as a communicator. Indicates that CA needs to be addressed before progress can be made in developing the communication skills of graduates to which employers attach considerable importance. Reports the results of a study comparing levels of CA amongst business and accounting students in the UK and Spain, which confirm the high levels of CA found in North American students but also indicate differences which may be due to cultural and other factors. Considers implications of findings for curriculum design and staff development.

Abstract
Purpose
To establish the existence of barriers to communication and numeracy skills development and to establish the levels of these exhibited by accounting and business students at the commencement of their courses in higher education.
Design/methodology/approach
Uses questionnaires to establish the levels of communication apprehension (CA) and maths anxiety (MA) in students at the commencement of their accounting and business courses in higher education. Establishes the underlying factors that are influential in determining the levels of apprehension and anxiety in individual students. An analysis of the underlying demographic variables such as age, previous educational background, etc. is also undertaken.
Findings
Identifies the existence of high levels of CA in accounting students and MA in business studies students at the beginning of their courses.
Practical implications
Where high levels of CA in accounting students and MA in business studies students are shown to exist consideration must be given to relevant curriculum design and delivery, and the use of techniques designed to reduce apprehension/anxiety in the students concerned. Because the apprehension/anxiety is present on entry to higher education it may be that specific courses appear to be recruiting students whose perception of their longer term vocational skills requirements may be inappropriate to their chosen career area.
Originality/value
Identifies specific differences in the areas of CA and MA between differently focused vocational courses, which have syllabus overlap, within a business school.

Abstract
Purpose
The purpose of this paper is to look at the adoption of double entry bookkeeping at the Royal Treasury, Portugal, on its establishment in 1761 and the factors contributing to this development. The Royal Treasury was the first central government organization in Portugal to adopt double entry bookkeeping and was a crucial first step in the institutionalisation of the technique in Portuguese public administration.
Design/methodology/approach
Set firmly in the archive, this paper adopts new institutional sociology (NIS) to inform the findings of the local, time‐specific accounting policy and practice at the Portuguese Royal Treasury.
Findings
Embedded within the broader European context, this study identifies the key pressures exerted upon the Royal Treasury on its formation in 1761, which resulted in major accounting change within Portuguese central government from that date. The study provides further evidence of the importance of the state in the institutionalization of accounting practices by means of coercive pressures and highlights for Portugal the importance of individual actors who, as powerful change agents, made key decisions that influenced accounting change.
Originality/value
This study examines a major instance of accounting change in European central government and broadens the application of NIS in accounting history research to a different country – Portugal – and to a different time – the eighteenth century. It also serves to illuminate the difficulties of collecting pertinent evidence pertaining to this long‐dated time period in identifying certain forms of institutional pressures.

Abstract
Purpose
This paper aims to describe the levels and type of contingency faced by school principals in Chile and the way certain aspects of the Chilean school system result in a greater or lesser presence of these contingencies.
Design/methodology/approach
The results reported here are based on the application of a structured questionnaire to 381 elementary school principals in Chile. A “Leadership Contingency Index” was created to analyze the extent and characteristics of this phenomenon, which was complemented with a multiple regression analysis to observe the variables that influence the levels of contingency.
Findings
This study has shown that the main contingencies faced by school leaders in Chile revolve around the relationship between actors: assist families, relationship with and among students and resolution of school staff problems. Also shows that the level of contingency faced by principals is strongly conditioned by the socio-educational context of the school and is not related to the individual characteristics of the leaders. This level of contingencies is significantly higher in the public system, although the most recurrent contingencies are the same in each type of school administration (public, private subsidized and privately funded schools).
Originality/value
This paper addresses an important but relatively unexplored dimension in specialized research on leadership: variable contingencies under which the leadership role is performed daily, including significant gaps between schools. Understanding and analyzing school leadership from the perspective of the complexity of tasks currently faced by principals, many of them highly unpredictable, ensures a realistic view of the possibilities and limitations of leadership in action and, consequently, provides better tools to strengthen the school leadership role and its contribution to improving student learning.

Abstract
Purpose
The aim of this study is to analyse teachers’ perceptions of information and communication technologies (ICT) and the effect they have on their students, comparing male and female teachers in rural and urban areas of Mexico.
Design/methodology/approach
This is a quantitative study with a validated questionnaire that records the perception of school teachers from a state in the northeast of Mexico. The questionnaire was designed by interviewing 20 teachers who have had problematic situations in the use of technology by students. The main problems that were perceived in their students were cyberbullying, cyberviolence, online pornography, excessive use of videogames and also lack of ability to use digital technology. Hypothesis testing was applied to identify differences between gender (female or male) and region (rural or urban), considering these problems and the efforts made by the school to address these issues.
Findings
Both the gender of the teaching staff and the region where the school is located are variables that are influencing the willingness to incorporate ICT issues that are affecting the well-being of students into the educational agenda. While teachers are the main actors in preparing their students on how to face these challenges, students in schools with mostly male teachers, or located in rural areas, will be in a situation of greater vulnerability to be victims of the problems that arise as part of ICT risks in a digital society
Research limitations/implications
This article only offers a first approach to ICT and teachers’ perceptions. It is necessary to broaden the scope of this type of research to include different educational contexts and to ask questions that reveal in greater detail how schools are dealing with ICT and its possible risks and the factors that have influenced the successes or failures they are having in these attempts.
Practical implications
This finding can help schools to promote programs focused to apply ICT for student flourishment and help them to deal with the risk that digital technology is generating in young students.
Originality/value
Although multiple research have been conducted to address teachers’ perception about diverse topics, there has been no specific research on the self-perception of teachers in dealing with technology and preparing students for the problems presented by ICT and its risks. This research contributes to the literature on the impact that teachers’ perceptions can have on the adoption of technology in education, and how this can be different by gender and region.

Abstract
Purpose
The extrusion-based additive manufacturing method followed by debinding and sintering steps can produce metal parts efficiently at a relatively low cost and material wastage. In this study, 316L stainless-steel metal filled filaments were used to print metal parts using the extrusion-based fused filament fabrication (FFF) approach. The purpose of this study is to assess the effects of common FFF printing parameters on the geometric and mechanical performance of FFF manufactured 316L stainless-steel components.
Design/methodology/approach
The microstructural characteristics of the metal filled filament, three-dimensional (3D) printed green parts and final sintered parts were analysed. In addition, the dimensional accuracy of the green parts was evaluated, as well as the hardness, tensile properties, relative density, part shrinkage and the porosity of the sintered samples. Moreover, surface quality in terms of surface roughness after sintering was assessed. Predictive models based on artificial neural networks (ANNs) were used for characterizing dimensional accuracy, shrinkage, surface roughness and density. Additionally, the response surface method based on ANNs was applied to represent the behaviour of these parameters and to identify the optimum 3D printing conditions.
Findings
The effects of the FFF process parameters such as build orientation and nozzle diameter were significant. The pore distribution was strongly linked to the build orientation and printing strategy. Furthermore, porosity decreased with increased nozzle diameter, which increased mechanical performance. In contrast, lower nozzle diameters achieved lower roughness values and average deviations. Thus, it should be noted that the modification of process parameters to achieve greater geometrical accuracy weakened mechanical performance.
Originality/value
Near-dense 316L austenitic stainless-steel components using FFF technology were successfully manufactured. This study provides print guidelines and further information regarding the impact of FFF process parameters on the mechanical, microstructural and geometric performance of 3D printed 316L components.

Abstract
Purpose
Fused filament fabrication (FFF) is one of the most popular additive manufacturing (AM) technologies due to its ability to build thermoplastic parts with complex geometries at low cost. The FFF technique has been mainly used for rapid prototyping owing to the poor mechanical and geometrical properties of pure thermoplastic parts. However, both the development of new fibre-reinforced filaments with improved mechanical properties, and more accurate composite 3D printers have broadened the scope of FFF applications to functional components. FFF is a complex process with a large number of parameters influencing product quality and mechanical properties, and the effects of the combined parameters are usually difficult to evaluate. An array of parameter combinations has been analysed for improving the mechanical performance of thermoplastic parts such as layer thickness, build orientation, raster angle, raster width, air gap, infill density and pattern, fibre volume fraction, fibre layer location, fibre orientation and feed rate. This study aims to assess the effects of nozzle diameter on the mechanical performance and the geometric properties of 3D printed short carbon fibre-reinforced composites processed by the FFF technique.
Design methodology approach
Tensile and three-point bending tests were performed to characterise the mechanical response of the 3D printed composite samples. The dimensional accuracy, the flatness error and surface roughness of the printed specimens were also evaluated. Moreover, manufacturing costs, which are related to printing time, were evaluated. Finally, scanning electron microscopy images of the printed samples were analysed to estimate the porosity as a function of the nozzle diameter and to justify the effect of nozzle diameter on dimensional accuracy and surface roughness.
Findings
The effect of nozzle diameter on the mechanical and geometric quality of 3D printed composite samples was significant. In addition, large nozzle diameters tended to increase mechanical performance and enhance surface roughness, with a reduction in manufacturing costs. In contrast, 3D printed composite samples with small nozzle diameter exhibited higher geometric accuracy. However, the effect of nozzle diameter on the flatness error and surface roughness was of slight significance. Finally, some print guidelines are included.
Originality value
The effect of nozzle diameter, which is directly related to product quality and manufacturing costs, has not been extensively studied. The presented study provides more information regarding the dependence of the mechanical, microstructural and geometric properties of short carbon fibre-reinforced nylon composite components on nozzle diameter.
